This project identifies the sources of deterioration of state highway functionality that occurs over time and what actions can be taken to preserve, recover, and enhance functionality. Functionality should be considered in all stages of a highway's lifecycle, and it should be protected, preserved, and-where possible-enhanced during the course of planning, growth and development, operations, and maintenance. This report provides guidelines through an extensive list of actions for how the Texas Department of Transportation (TxDOT), metropolitan planning organizations, local jurisdictions, and other transportation stakeholders and agencies can protect, preserve, and enhance the functionality of the state highway system. TxDOT has two basic choices to address functionality of the highway system and its component highways: (1) preserve functionality at a high level through effective planning, operational and safety management, refinement, and proactive infrastructure maintenance; or (2) adopt a reactive and corrective approach to fix things after they deteriorate. Functional preservation is more cost-effective and alleviates the need for as many major projects, many of which take years to get through programming and project development.
